. constructing scaifoldings.

The invention consists of the construction and novelcombination of parts fully described and claimed hereinafter.

In the accompanying drawings, Figure l is a side elevation of the improved bracket. Fig. 1 is a detail in top plan of a part indicated in the preceding figure, and Fig. 1 a section on the line a: 00 of said Fig. 1. Fig. 2 is a front view of same in place on a ladder. Fig. 3 is a rear view of Fig. 2. Figs. 4 and 5 are side elevations of the device applied to inclined ladders.

Referring to the drawings, A is an ordinary ladder.

a is a supporting-bar, preferably made of U-iron and the upper end of which is provided with a suitable double hook e, to which is hinged at 'n a lever at, having a curved lower end and carrying a stirrup f, extending through the main part a. The stirrup f is provided with obliquely-arranged slots, Fig. 1, and serves to secure the lever cl on a step of the ladder by means of a pin.

Hinged at m to the upper end of the bar a, under the hook e, is an arm 0, pivotally connected by means of a brace-bar c to a slide block 71, provided with two perforations corresponding to holes gin the bar a for the purpose of enabling the lower end of the bracebar 0 to be adjusted vertically. The slideblock h is locked in position by means of a pin 1', extending through said slide-block and held in place by means of a cross-pin k.

In practice the improved bracket is used as follows: The hooks e are fitted over a step of the ladder and the lever d is pressed against the next step, the stirrupf being then locked by means of a pin. stirrup f are arranged obliquely for the purpose of enabling said stirrup to be locked on steps of varying shape and thickness. Hereupon the arm 0 is adjusted to the desired position by properly adjusting the slide-block h and locking same by means of the pin '5. It will be noted that the load is always supported on the steps of the ladder.

Having fully described my invention, what I claim, and desire to secure by Letters Pat- 6o ent, is-- 1. In combination with an ordinary ladder, an adjustable bracket, comprising a hooked supporting-bar adapted to be held on a step of the ladder and applied against the latter,

a lever hinged to the upper end of said bar, a stirrup carried by said lever and adapted to fit over a step of the ladder, means for looking said stirrup in place, an adjustable arm hinged to the supporting-bar and adapted to support the platform, and means for adjusting said arm, substantially as set forth.

2. In combination with an ordinary ladder, an adjustable bracket, comprising a hooked supporting-bar adapted to be held on a step 0f the ladder and applied against the latter, a lever hinged to the upper end of said bar, a stirrup carried by said lever and adapted to fit over a step of the ladder, means for looking said stirrup in place, an adjustable arm hinged to the supporting-bar and adapted to support the platform, a supporting-bar, a

brace-bar pivotally connected to said arm and said slide-block and means for locking the slide-block in adjusted positions, substa tially as set forth.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
